FRESH WATER ANCHOR ICE ALONG AN ARCTIC BEACH

Anchor ice is broadly defined as "submerged ice attached or anchored to the bottom, irrespective of the nature of its formation". We discuss here a form of anchor ice of which we can find no previous description. Where it coud be seen, the surface was striated, apparently by gravel frozen into moving ice blocks, but no gravel was found in the body of the fresh-water ice itself. Grounded floes covered part of the belt and in some places there was a thin covering of loose gravel on its upper surface which had been deposited by the melting ice grounded on top. The lower surface of the anchor was continuous with interstitial ice in the undisturbed gravel of the sea bed.
